When it comes to powering your gaming rig, selecting the right power supply unit (PSU) is crucial. Two formidable contenders in the PSU arena are the Corsair CX and RM series. In this comprehensive guide, we delve into the depths of the Corsair PSU CX vs RM debate, comparing their features, performance, and suitability for various needs.
The Contenders: Corsair CX vs RM
Corsair CX Series
The Corsair CX series is an entry-level PSU lineup designed for budget-conscious builders who prioritize affordability and reliability. These PSUs feature a no-frills approach, offering essential power delivery with a focus on stability and durability.
Corsair RM Series
In contrast, the Corsair RM series caters to more demanding users, including gamers and enthusiasts. These PSUs boast higher wattage capacities, superior efficiency ratings, and a host of advanced features, making them ideal for powering high-performance systems.
Performance Comparison
Power Output
Both the CX and RM series offer a wide range of wattage options, from 450W to 1200W. However, the RM series extends its offerings to 1600W, providing ample power for even the most power-hungry systems.
Efficiency
The RM series shines in terms of efficiency, achieving 80 Plus Gold or Platinum certification across its lineup. This means that these PSUs convert more of the incoming power into usable energy, resulting in lower energy consumption and reduced heat generation. The CX series, on the other hand, offers 80 Plus Bronze certification, which is still respectable but not as efficient as the RM series.
Voltage Regulation
Voltage regulation refers to the ability of a PSU to maintain a stable voltage output even under varying loads. The RM series excels in this aspect, with tighter voltage regulation than the CX series. This ensures that your components receive a consistent and reliable power supply, minimizing the risk of system instability or damage.
Features and Connectivity
Modular vs Non-Modular
The CX series PSUs are non-modular, meaning that all the cables are permanently attached. This simplifies installation but limits flexibility and cable management options. In contrast, the RM series PSUs are fully modular, allowing you to connect only the cables you need. This provides a cleaner and more manageable setup, especially in space-constrained builds.
Protection Features
Both the CX and RM series PSUs offer a comprehensive suite of protection features, including over-voltage, under-voltage, over-current, short-circuit, and over-temperature protection. These safeguards ensure the safety of your components and prevent damage in the event of electrical anomalies.
Fan Noise and Cooling
The RM series PSUs feature a semi-fanless design, which means the fan only spins when necessary. This results in near-silent operation at low loads, reducing noise pollution in your system. The CX series PSUs, however, have a continuously running fan, which can be noticeable under heavy loads.
Warranty and Support
Both the CX and RM series PSUs come with a generous 10-year warranty from Corsair. This provides peace of mind and ensures that you’re covered in case of any defects or failures. Corsair’s customer support is also highly regarded for its responsiveness and effectiveness.
Which PSU is Right for You?
The choice between the Corsair CX and RM series PSUs depends on your specific needs and budget.
Corsair CX Series
- Ideal for budget-conscious builders who prioritize affordability and reliability.
- Suitable for entry-level or mid-range gaming systems with modest power requirements.
- Non-modular design simplifies installation but limits flexibility.
Corsair RM Series

Beyond the Comparison: Other Considerations
Form Factor
Both the CX and RM series PSUs are available in the ATX form factor, which is the most common size for desktop PCs. However, the RM series also offers a compact SFX form factor, designed for smaller builds or HTPCs.
Price
The Corsair CX series is generally more affordable than the RM series. However, the price difference varies depending on the specific wattage and features offered.
Aesthetics
The RM series PSUs feature a more premium aesthetic, with blacked-out designs and customizable RGB lighting. The CX series PSUs have a more utilitarian appearance, with a focus on functionality over aesthetics.
Wrap-Up: Powering Your Choice
The Corsair PSU CX vs RM debate boils down to your individual requirements and preferences. If you’re on a budget and prioritize affordability, the CX series is a reliable choice. However, if you demand high performance, efficiency, and advanced features, the RM series is an excellent investment that will power your gaming rig for years to come.
